A key component of an LXI certification is the IVI device driver (Interchangeable Virtual
Instrument). Here IVI.NET drivers are provided, which are based on the .NET frame-
work 4 of Microsoft. LabView and LabWindows/CVI drivers built on LabWindows/CVI
2012 are also available. The latest copy of the IVI.NET driver is available for download
form the product homepage http://www.rohde-schwarz.com/product/nge100b.
In addition to the features described above, the device provides the following LXI-rela-
ted functions:
●
Displays the current device settings
●
Remote control of the device within the WEB-Browser
The Ethernet interface has an integrated web server, you can access the instrument
with its corresponding IP address in the address line of the browser (i.e. http://
172.25.57.65). See

6.1.5 SCPI
SCPI (Standard Commands for Programmable Instruments) commands - messages -
are used for remote control. Commands that are not taken from the SCPI standard fol-
low the SCPI syntax rules. The instrument supports the SCPI version 1999. The SCPI
standard is based on standard IEEE 488.2 and aims at the standardization of device-
specific commands, error handling and the status registers. The tutorial "Automatic
Measurement Control - A tutorial on SCPI and IEEE 488.2" from John M. Pieper (R&S
order number 0002.3536.00) offers detailed information on concepts and definitions of
SCPI.
The requirements that the SCPI standard places on command syntax, error handling
and configuration of the status registers are explained in detail in the following sec-
tions. Tables provide a fast overview of the bit assignment in the status registers. The
tables are supplemented by a comprehensive description of the status registers.
